It is generally the custom for public utility companies that supplycommunities with electrical current and gas, to furnish their numerousvsubscribersvwith a periodical statement of their aci counts. Inaddition to furnishing statements of accounts to subscribers, a recordof those accounts is also kept by the company, and, in the present case,such a record is printed by the machine on an audit strip havingmechanism for n giving the proper feed to the strip at the proper time,depending upon the type of operation being performed by the machine.

Therefore it is broadly an object of this invention to provide a. cashregister which will simultaneously print various data and amounts in theseveral columns on record material.

Another object of the present invention is to provide novel means forfeeding the audit strip.

A furtherobject is to furnish novel and selective mechanism controlledby the transaction keys and the total keys for controlling the auditstrip .feeding mechanism and the impression mechanism. v

All the mechanism pertinent to the present invention will now bedescribed in detail.

DETAILED DEsCRIr'rroN The present invention is embodied in the type ofregister illustrated and described in the patents referred to at thebeginning of this speeliication. As machines of this character are wellknown in the art, the mechanism thereof having no direct bearing on thepresent invention will be but brieny describes.

Machinefmmeworc and operating mechanism Calling attention to Figs. 2 and3, the mechanism or the machine proper is supportedby two main framesdii, only one (the left frame) being here shown, and various otherintermediate frames, cross frames, and braces` The main frames are inturn secured to a machine base lli and the entire machine is enclosed ina suitable cabinet El@ also secured to the maciiine base As a generalrule,.the machine is operated by means of the usual electric motor' (notshown) which is operatively connected to the main drive shaft @il by theusual clutch mechanism and 'gearing'.

Depressine the usual motor bar bil (Fia. l) releases a lacy lock shalt@il (Fig. 2) for a slight clockwise movement under influence of aspring. This movement of the shaft lil engages the clutch mechanism andcloses the electrical circuit to the motor, thereby causing the machineto operate. Near the end of the machine operation, the shaft if! isrocked counter-clockwise to release the depressed keys, disengage theclutch mechanism, and simultaneously open the motor switch in the usualmanner.

if desired, or when electrical current is not available, the machine maybe operated by means of a hand crank which is operatively connected tothe main drive shaft t2 by means of a train of gears. Depresslng thestarting bar t@ (Fig. l) releases the shaft 52 for rotation, asexplained hereinbefore. The machine may then be operated by turning,rthe hand crank.

As the motor. clutch, and releasing mechanism are of conventional designand old in the art, they Ahave not been illustrated herein and will notbe further described. However, reference may be had to the ShipleyPatent No. 1,- 761,542 issued June 3, 1930, for a full disclosure ofthis operating mechanism.

.Keyboard totalioers.

dierent totaliaers for engagement with their actuators in a manner laterto be described. is presently constructed, the machine of this inventionhas nine rowsof amount keys to, which control the positioning of thedierential actuators in the well linown mennen'.

Amount loog/s ond dirla-entice? mechanism As previously stated, themachine of this lnvention has nine banks tu of amount keys t, and, asall the amount banks and their assoelated dierential mechanisms aresimilar, it is thought that the descriptionoi one 'denominational unitwill be sulcient for the purpose of this invention. g

Referring to Fig. 2, the amount key banks t@ are removably supported onrods iii and h2 extending between and supported by the main machineframes Et. Pivoted on the lower end oi each amount bank is a zero stoplever @t having a right-angled projection arranged to cooperate with theforward end of a reset spider i pivoted on a hub B5 or an amountdinerentlal actuator 6d. The actuator @t is loosely mounted on a hublill extending between two dierentlal support plates d@ (only one hereshown) supported- Mounted for lateral shifting movement by.

Sii

means ci' the arm 'iii and a similar arm lli, is a dierential latch i3,a foot-shaped. projection ci which is arranged to cooperate with adifferential driving segment it pivoted on the hub iil, and connected bya link 'le to a' lever it journaled on a stud il"` secured in one of theplates @il The lever l@ carries a pair of rollers l@ which cooperatewith the peripheries of companion cams i@ and @il secured on the maindrive shaft h.

In adelineI operations, the shaft @il and the cams i9 and il@ make onecomplete revolution clockwise, which, by means ofthe lever it and thelil, rocks the driving segment lil first in a clockwise direction andthen back to normal position.

As previously stated, there is :a dlerentlal actuator unit like thatexplained above for each amount bank, and each diiierential unit issupported between two oi the plates ttl. The coinplete assembly offdierential units are held together by means ci a rod @l extendingthrough the hubs I? no isey is depressed in an amount bank, the zerostop lever @t engages the forward end of the reset spider @fi to rockthe latch arm lli counter-clockwise to move the dierential latch 7Sforwardly, thereby disengagina the foot thereof from the depression inthe dri segment le and engaging a' nose et oi said latch with one oi aseries ci notches @t in a plate @il eecured to one of the plates t6.This stops the diirerential-actuator @it in zero position by disensagingsaid latch from the driving segment iii.

The concentric portion ci the segment llt, in cooperation with the footoi the latch 822. mainioins the nose ci said latch in engaaeent with theplate @il while said segment completes its initial movement 'clockwiseand during the l:sis

greater part of the return movement of said segment'until the depressiontherein is opposite the foot of the latch 82. When the depression isopposite the footof the latch 82, a flat surface of the segment 14engages a stud 85 in the actuator 66 and returns said actuator to homeposition, thereby disengaging the reset spider 64 from the zero st oplever 63 and allowing a spring 86 to disengage the nose 82 of the latch13 from the notch in the plate 84 and to reen'gage the foot of saidlatch with the depression in the driving segment 14.

Depressing one of the amount keys 59 forces the lower end of the stemthereof into the path of the latch arm 1|. Consequently, initialmovement clockwise of the segment 14 and the actuator 66'causes said arm1| to engage the stem of said key to disengage the foot of the latch 13from the segment 14 in exactly the same manner as explained above. Onits return movement the segment 14 engages the stud 85 to return theactuator 66 and disengage the latch 13, as described above.

It will be also understood that depression of an amount key 59 rocks thezero stoplever 63 counter-clockwise out of the path of the spider 64,thereby 'allowing the actuator 66 to travel clockwise until stopped bythe depressed amount '88 in a link 89, the upper end of which is pivotedto an indicator segment' 90 supported by one of a series of indicatortubes 9| on an indilcator shaft V92, opposite ends of which aresupported by the main frame 50. The lower end of the link 89 is pivotedto a printer segment 93" turnably supported on a rod 94, opposite endsof which are carried by the main frames 50.

After the actuator 66 has been positioned under the control of adepressed amount key, as

explained earlier herein, orunder the control of the totalizer wheel intotal taking operations, in a manner later to be described, a roller 95carried by the lever 16 engages an arcuate surface 96 of the beam 81 toforce an arcuate surface 91 of said beam into contact with the hub 65.This, by means of. the link 89, positions the segments 90 and 93commensurate with the position of the actuator 66. The segments 90 and93 in turn position the indicator mechanism and the printing mechanismi`n accordance with the amount set up onvthezkeyboard or in total takingoperations in accordance with the amount on the wheel of the totalizerbeing read or reset. Later on in this specification, the manner in whichthe segment 93 positions thetype wheel will 'be expIai-ned.

An alining bar 98 (Fig. 2) cooperates with the Totalizers andtransaction keys By observing Fig. z it will be seen' that lthepresent-machine has three lines of .totalizers, an

uppertotalizer 99,' a reartotalizer |00, and ai front totalizer Theupper totalizer 99 is an add-subtracttotalizer and has an add wheel anda subtract wheelV |02 for each denominationall unit, said wheelsbeingreversely geared together so that one is always complementary tothe other. In addition to the adding and subtracting wheels |02, theupper totalizer line has a plurality of sets of adding. Wheels whichfunction in exactly the same manner as the front and rear totalizerwheels. The `wheels of the upper totalizer line are shiftable laterallyin relation to the actuators 66 under control of the rst row oftransaction keys 56 in the usual manner.

The rear and-front totalizer lines each carry a plurality of sets oftotalizer wheels |03 adapted to be selected, in the usual and well knownmanner, for alinement with the actuators 66 by the second and third rowsof transaction keys 51and 58 respectively. There is also a set of grandtotalizer wheels on the front totalizer line arranged to be selected bydepression of any of the keys .51 in the second transaction bank and asimilar set of totalizer wheels on the rear totalizer line selected in alike manner by the keys 58 in three'totalizer lines in the regular way.

Directing attention to Fig. 3, which is a sectional view of the firsttransaction bank and which is representative of all the transactionbanks, it will be noted that the transaction banks have alatch mechanismsimilar to 'the amount latchl mechanism. This latch is broken orreleased in'zero position by'zero stop lever |06 and in other positionsunder control of depressed transaction keys 56. 'I'he transaction latch|05 carries aV beam |01 which, by means of a link |08,

vdiilerentially positions the, transaction indicator segment |09 securedon the shaft 92 and a printer segment ||0 loose on the shaft 94.

In adding operations, selecting disks (not shown) controlled by. thetransaction banks cause the selected set of totalizer wheels tobeengaged with the actuators 66.immediately after said actuators havecompleted their clockwise setting movement as' explained earlier'herein. Return movement counter-clockwise of the actuators rotates thewheels of the selected totalizer I'n total taking operations thedifferent sets of l totalizer wheels on the different lines are'selected and alined with the actuators 66 by means of the transactionkeys 56, 51, and 58 in exactly the same manner as'described for addingoperations.

In total taking operations theA different totalizer lines are selectedfor engagement withv the actuatorsA 66 by means of the total controlkeys 55 (Fig. l). For example, depressing the first bank read key inconjunction with one of theA first transaction keys 56 will select thecorrespondingtotalizer on the upper .totalizer line for a readingoperation. Likewise, using the -lrst bank resettotalizer control key inconjunction with one of the keys 56 selects the corresponding totalizerof the upper totalizer line for a resetting opera- In the presentmachine, adding operations are performed in one cycle of movement ofythe machine and total taking operations require two cycles of movement.In the rst cycle of movement of a total taking operation, the wheels ofthe vselected totalizer are alined with the actuators 66. Likewise, inthis rst cycle of movement the zero stop levers t2 (Fig. 2) break allthe amount latches in zero position. At the beginning 'of thesecondcycle of a total taking operation the selected totalizer is'engaged with the actuators $6 and the zero stop levers 63 are rocked.out of the path of the spiders et. Clockwise movement of the actuatorsrevolves the wheels of the engaged totalizer in a reverse directionuntil they are stopped in zero position by means of a long tooththereon. This positions the actuators commensurate with the amount onthe totalizer wheels and return movement counter-clockwise of theactuators in turn positions the indicating and printing mechanisms inaccordance with the amount on said totalizer wheels.

In reading operations the wheels of the selected totalizer remain inengagement with the actuators 65 during their return movementcounter-clockwise. This rotates the wheels back to their originalpositions. In resetting operations the -totalizer is disengaged fromthe` actuators 65 before said actuators start their return movementcounterclockwise, thereby leaving the totalizer wheels standing at zero.The usual transferring mechanism is employed for transferring amountsfrom lower to higher denominations.

Printing mechanism The method of driving the columns of type wheels isby means of ring gears having external and internal teeth. The ringgears are diierentially positioned by means of their external teeth andpinions driven by internal teeth there- In its present embodiment theinstant machine is arranged' to print various data and amounts in aplurality of columns on a statement sheet and on a detail strip in asingie operation of the machine. This necessitates the identical settingof a series of type carriers and the method disclosed in the patentreferred to above is ad.- mirably adaptedfor use in driving a columnprinting mechanism of this type. Due'to the fact that the printerdriving mechanism is substantially duplicated in each denominationalunit, it is thought that the explanation of one denominational unit andone transaction blank will be sufcient for the purpose of thisspecification.

Directing attention to Figs. 3, l2, and 13, a link H3 pvotally connectsthe segment Mt to an arm Ht secured on a shaft |05 journaled in the mainframeset. Also 'secured on the shaft H5 is a gear segment llt whichmeshes with a ringr gear rotatably supported on a disk ||B fast on ahexagonal shaft H9 supported by printer end plates |2|, only one beingshown, and intermediate plates |23, only one being shown. The upper endsof the plates |20, |2|, |22, and |23 are supported by a bar |26 securedto the main frames 51|! and their lower ends are secured Vto extensionsof the base plate 5|. The gear y aieaaso (Figs. 3 and 12) has securedthereto a-genr which meshes with a pinion |26 fast on a shaft |28 whichalso carries a pinion |22 meshing with a gear ||2 fast to the side ofanother ring gear |25. Therefore, movement of the gear is transmitted tothe gear |25 by means of the gears and H2, pinions |26 and |21, and theshaft |28. The gear |25 meshes Awith a first transaci 1 tion typecarrier |29 loosely mounted on a-'shaft A|30 xedly supported by The typewheel operating mechanisms for theA second and third transaction bankswill not be described in this divisional case.

Selecting mechanism Selecting mechanism `controlled by the firsttransaction bank and th -total control keys 55 (Fig. l) control theoperat ngofmthe impression hammers and the feeding of th detail strip.

'By observing Figs. 3 and 6 it( ll be remembere-d that' the Shaft alsisv differentially positioned in accordance with the t transaction banklatch, and that the shaft Sii/i differentially positioned commensuratewithfthe total control plate |68 through `thelink lll and a |16. Also,by means of an arm |'|8, link |19, egment |80, ring gear IBI, and disk|82, an X and Z or read and reset type Wheel |82 is positioned by thetotal control plate |68.

Securedon the shaft H5 (Fig. 4) is al gear segment 2|5 which eshes/ withan intermediate gear 2|6 loose on a s ud 2|? secured in an auxiliary endframe 2| 8 supported by the base 5|. The gear 2 i6 meshes With-afpinion2li secured on a shaft 22o (Fig. 14) journaled in printer` frames 22|and 223 secured in xed relation to each other by bars 2||l and 2|secured to a machine subbase (not shown).

secured on the shaft se (Figs. 4y and 5)4 which:

it will be recalled, is differentially positioned by the total ycontrolplate |58 is a gear segment 225 which meshes with anlintermediate gear226 loose on the stud 2|? and which in turn meshes with a pinion 221(see also Fig. le) secured to a gear 22B, both of which are rotatablysupported bythe shaft 22D. The gear 222 meshes with a pinion 229l whichdrives a shaft 230 journaled in the frames 22| and 223. From theforegoing description it will be seen that the shafts 22|! and 23|!(Fig. 4) are differentially positioned respectively by means of thefirst bank of transaction keys 56 (Fig. l) and by the total control keys55.

Impression hammer selecting and operating mechanism Fig. 7 illustratesthe impression selecting and operating mechanism for one columnar unitof the column printer. As the mechanism is substantially duplicated ineachcolumn of theprinter, including the audit strip section of theprinter,

it is felt that the description of one such columna unit will besuiicient for all.

Each impression unit has two selecting disks 23| and 232 (Figs. 7 and14)I the former secured on 24| secured on the shaft 239, and said spring243 normally maintains4 a raised lower portion of the lever 238 incontact with a stud 242 carried by the arm 24|. A link 243 pivotallyconnects the lever 238v to a link 244, the rearward end -of which ispivoted to a bell crank 245 loose on a rod 245 supported by the frames22| and 223. The bell crank 245 carries rollers 241 and 240, whichcooperate respectively with the' peripheries of companion cams 240 and250 secured on a shaft journaled in the frames 22| and 223.

Referring to Fig. 4, secured on the right hand end of the shaft 25| isagear 252 which meshes with an intermediate vgear 253 rotatably supportedby a stud'254 carried by the plate 2|8. The intermediate gear 253 inturn meshes with a gear 255 secured on the right hand vend of a printerdrive shaft 2|4 journaled in the right frame 50 and the auxiliary frame2|8. The shaft 2|4 is diametrically alined with the main drive shaft 52vand is operatively connected thereto by a clutch mechanism (not shown).

It will be recalled that in adding operations the main drive shaft 52makes one completer clockwise rotation and in total taking operations itmakes two complete clockwise rotations. In order to 'prevent theprinting mechanism from making anunnecessary operation Vin total takingI operations,v the shaft 2|4 is automatically declutched from the shaft52 during the first cycle of total l taking operations. Consequently theshaft 2|4 makes only one clockwise revolution. in adding and totaltaking operations and due to the fact that the 'gears 252 and 255 areidentical, the shafts 2|4 and 25|'move in synchronized relation. V

Again directing attention to Fig. 7, theforward endof the link 244 hastherein' a notch 255 whichcooperates with a stud 251 fast in a lever 258turnably mounted on a rod 250 supported by the frames 22| and 223. Atoggle link 250 pivotally connects the lever 258 to an impression hammerr25| (Fig. '1) rotatably mounted on a rod 252 also from the left of themachine.

shaft 233 (Fig. `.14)4 is an arm 254 having pivotedV supported by theframes 22| and 223. The hammer 25| carries an impression block 253adapted to cooperate with onecolumn of type wheels V on the line |30 tomake impressions on' material inserted between said impression blocks253 and said type wheels. f

Fig.l11 shows the shafts238 and 25| as observed thereto a pitman 255,the rearward end. of which is bifurcated to straddle the shaft 25|. Thepitman 255 carries-a' roller 255 arranged to cooperate with a cam groove251 in a box.- cam 250 secured on the shaft 25|.`

In the initial part of machine` operations, the selecting plates 23|yand 232 (Fig. 'Il are differentially positioned by the mechanism shownin Fig. 4. Immediately thereafter the shaft 239 isrockedcounter-.clockwise as observed in Fig. 7

(clockwise as viewed in Fig. 11) by means of the mechanism shown in Fig.11. If an undercut portion of the plates23| or 232 is opposite thefeeler projections 235 or 235, the spring 240 will move the lever 238 inunison with the arm 24| to disengage the notch in the forward end oftheV link 2&1 from the stud 251. Therefore, when the companion cams 248and 250 rock the bell crank 245 mst clockwise and then back to normalpo- Secured on vthe sition, the link 244 will move idly back and forthwithout imparting any movement to the impression hammer 25|. Anextension 21| of the link 244 insures that the lever 258 is in its homerposition after an operation'in which its associated hammer 25| isdisabled Y However, if the largest diameter of the plates 23| and 232 isopposite the feeler tips or projections 235 and 235, counter-clockwisemovement of the lever 230 will be effectively blocked and' the shaft 239and arm 24| will move independently thereof, exing the spring 240.Consequently the notch in the link 244 will be retained in engagementwith the stud 251 and initial movement clockwise of the bell crank 245,as explained above, will, by means of the link 24'4, rock the lever 258,and, by means of the togglelink 260,

`tions of the plates 23| and 232 and their`relation to the feelerprojections 235 and 2354 are varied -to properly control the printing ofthe columns they represent. In some of the columns these'- lectingplates 23| positioned by the total plate |50 alone control the operationvof the hammers. In such cases the first transaction bank exercises nocontrol whatsoever over the impression mechanism.

Audit or detail strip feeding mechanism Most of the audit strip feedingmechanism is contained between the frames 22| and 223- (Fig. 14), whilea small portion of the mechanism ismounted on the outside of the frame22 I.

In the initial part of machine operation, a laterally slidable tablemoves a portion of the audit strip, wound therearound', rearwardly intoprinting position. After the impression is made, the slidable table isreturned forwardly to return the audit strip from the impressionmechanism so that the last impression thereon'will be visible. After theimpression is made and while' the audit strip is being thus returned, thfeeding l thereof takes place.

. Like the impression operating mechanism and the statement slip feedingmechanism,l the audit strip feeding mechanism is under the selectivelcontrol of the first transaction bank and the total control keys.

'I'he audit strip receiving roll or reel is driven by ,a slippage memberwhich insures the fed amount of the strip beingwound thereon regard- -l401 provides a drag on the hub 405 to preventl l the supply roll fromunwinding Atoo freely. 'I'he web of the audit strip is threaded aroundafianged roll 403 loose on astud 403 secured in the. frame 223, thencearound another angedroll 4|. supassenso ported by right-angled ears ofan audit strip table di i. lThe audit strip is then carried across theface or the table (il i, thence around a roller #M2 supported at therearward end of the table iii in the same manner as the roll ii d. Theweb of the audit strip continues around e. feeding roll 363 and from thefeeding roll it is attached to and wound upon a4 supply roll die `bymeans of a key sie in the well known manner.

The table di i is supported for horizontal sliding movement between theframes 229 and 223 by means of opposed plates die and tie secured on thebent-over sides of the table dit and located near oppositeends thereof.The plates fi i 5 and MS each have slots adapted to receive rollers lilloose on studs die. two of which are secured in the frame 22@ and'two inthe frame 22d.

The audit strip table @il (Figs. 9 and le) carries a bracket et@hifurcated to receive a stud @2i in a cam arm e222 loose on a stud diesecured in the frame eti. The arm @22 carries a roller d2@ whichcooperates with a cam groove 32E in a box earn We secured on the shaft25|. Fast in the arm @22 is a stud 321 which cooperates with anextension 628 of a yoke $29 rotatably supported on a rod itil extendingbetween the frames 22| and 223. The yoke Q29 has downwardly extendingarms dei, bifurcated to straddle studs Q32 carried by bellcranks 4&3 and35 loose on the rod 680. The bell cranks 633 and 63@ carry rollers Q33adapted to grip the audit strip 603 against the feed roll @i3 in amanner presently to be described.

, The feed roll dit (Figs. 15 and 17) has tenons which engage a clutch631, cut in the hub of a gear @38, loose on the rod dat. The gear 638 isoperatively connected, by a pinion 439 loose on a stud M0 secured in theframe 22E, to a gear 44| loose on a stud 442 secured in the frame 223.Said stud M2 also rotatably supports the receiving reel 4|@ (Fig. 16).Secured to the gear MI is a plate 4&3 to which are pivoted the lowerends of symmetrical segments M6, between `the upper free ends of whichis stretched a spring ME. Concentric internal arcuate surfaces 446 ofthe segments 444 cooperate with the periphery of a disk 441 (see alsoFig. secured to the reel 4M.

` Secured between the disk M1 and the reel le is a ratchet wheel 448,adapted to cooperate with a paw] 465 pivoted on a plate 460 turnablysup- Ported on an undercut portion of the reel 4|4 between the ratchet448 and said reel SIG. The pawl 4&9 has a tail 45| which cooperatesvwith a projection G52 of a link 'pivotally connecting the plate '45u toan' arm 454 secured on the left end of a shaft 45E, opposite ends ofwhich are Y Journaled in the frames 22| and 223. Secured on the righthand end of the shaft 655 is an 'arm 458 to which ispivoted one end of alink, 451 having therein a slot through which extends a stud 4&9 securedin the extension 34d of the frame 22| (see also Fig. 14). An upturnedextension 489 on the link 451 protrudes through an opening l in themachine cabinet and forms a convenient er piece for operating the audit`stripreceiving reel by hand. y

For the link 651 (Figs. 10 and 15) rearw :fi y revolves the plate ed@and lowers the pro- 1 Jection des of the link @52 to allow the pawl et@to engage the ratchet ed@ lunder tension of a spring dei. Continuedrearward movement of the del revolves the plate de@ counter-clockwise adistance determined by the stud et@ in i cooperation with the siot'inthe link (im. This.

hy means of the pawl die, also revolves the ratchet M8 and the reel diea like distance counterclockwise to hand-feed. the audit strip. A spring@G2 returns the link tt forwardly to normal position to disengage thepawl et@ from the ratchet M6.

An intermediate gear d66 (Fig. 17) pivoted on a stud secured in theframe 223 operatively connects the gear (i3d to a pinion del securedto'a Geneva gear 5&8 loose on the shaft 53d. The Geneva gear d68 has aplurality of U-shaped slots ed@ which cooperate with a stud lill@ fastin a plate 11 loose on the shaft 2M (see also Figs. 18 and 2li). Securedto the plate @1i is a Geneva disk |512, the periphery of which isadapted to cooperate with a series of arcuate surfaces e313 (Fig. 1'?)of the ,Geneva gear @S8 to retain said Geneva gear in position when itis not being actuated hy the stud die.

Referring to Figs. 19, 20, and 21, integral with the plate 51E and thedisk i112 is a huh Mtl slotted to receive tenons Q of a driving plateelle secured on the shaft A raised portion ell of the face of the hub511i cooperates with a camming lug 518 on the face of a bushing 519secured in the frame 223 and forming a bearing for the shaft 25|. Thebushing 419 has sym- AInetrical Yslots d8@ which cooperate with tenons418| oa bushing 682 loosely supported by the hub du and retained inposition by means of av flange 83 on the bushing gfwhich ts loosely inan annular groove formedfbetween the huh e761 and the disk M2.

Secured on another ange of the bushing 482 is a plate 484 connected by alink 485 to a lever 86 (Fig. 18) loose on the shaft 239 and exiblyconnected by a spring 481 to an arm 688 secured on the shaft 239. Thelever $86 has pivoted thereon a feeler 489 with projecting ngers 4" andthe plate 41E in unison with said shaft 28|. This causes the stud 412 onthe plate'l to engage one of the U-shaped notches 468 in the Geneva gear488 to rotate said Geneva Lgear one increment of movementcounter-clockwise. A cut-away portion G96 of the periphery of the disk412 provides the clearance necessary to allow the Geneva gear 468 torotate. Counterclockwise movement of the Geneva gear 448 by means of thepinions 681 and 46B rotates the gear 438 and the i'eed roll M3 (see alsoFig. 15),. The gear 438, by means of the pinion 439, rotates the geardei and the plate dei also in a counterclockwise direction. The segments'4&4 in frictional engagement with the disk 641 (Fig. 10)

vrotate the receiving reel die in unison with the plate 418 and the hub414,drives the-disk 412 amitieev y '7 continue to hold the audit strip498 in contact with the feed roll 4|8 whilethe Geneva gear 488 is beingrotated by the stud 419, which, as ex plained above, also rotates thefeed roll and the receiving reel 4|4 inl a counter-clockwise direction.This causes vthe feed roll 4|3 to unwind the audit strip web from thesupply reel A403 after the impression mechanism has functioned' andwhile the audit strip table 4|| isbeing returned forwardly to norma-lposition. As fast as the audit strip is fed by the feed roll 4|3 it iswoun on the receiving reel 4| 4.

'Ihe fact that the'audit strip feed is the same eachmachine operationandthat less movement of the receiving reel is required to-wind the fedportionof the strip thereon when the diameter of the receiving rollincreases, necessitates the friction connection, just described, betweenthe plate 443 (Fig. 1'1), which has a constant or fixed movement eachmachine operation, and the receiving reel 4|4, the movement of whichvaries with the 'circumference of the receiving roll. Therefore, afterthe fed amount of the audit strip has been wound around the receivingroll, the shoes or segments 444 -slip around the periphery of the disk441 (Figs. 10 and 16) without imparting further movement to saidreceiving reel As in the case of the statement slip, it is sometimesnecessary to make several impressions on a single line of the auditstrip and this necessitates control of the feeding mechanism, which isaccomplished by means 'of'the selecting plates 482 and 493 (Figs. 15 and18) and cooperating mechanism'. Before the Geneva gear 468 receives itsfeeding movement, the shaft 239 and arm 488 are rockedcounter-clockwise; as previously explained. If an undercut portion ofthe disks 492 or 498 is opposite the fingers 499 and 49| of the feeler489, the lever 486, by means of the spring 4,81, is moved. in unisonwith the arm 488. This, by means of the link 485, shifts the bushing 482(Figs. 20 and 21) counter-clockwise to the hub 414 .moves beyond the lug418. This al-` lows a plurality of springs 498loose onl studs securedinthe plate 41| and compressed between said plate 41| and one of theaudit strip hammer operating cams 249 to shift the entire unit.consisting of the plate 41|, disk 412, hub 414, and the bushing 482,toward the left,`thus causing the lugs 48| to enter the slots 488 in thestationary bushing 419. This shifts the vstud 419 into alinement withthe Geneva gear 498 and also moves the recessed. portion 498 of the disk412 opposite the Geneva gear so that said stud 410 will engage androtate said Geneva gear and associated mechanism to feed the audit stripin the manner.,

set out above. Immediately after the feeding takes place, the

. raised portion 411 of the hub 414 engages the camming lug 418 to shiftthe audit strip feed operating unit toward the right to ineffectivepol480 in the bushing 419 prior to return movement clockwise of theshaft 289 and the arm488. 'I his allows the arm 488 to restore'the lever488 to normal position, as shown in Fig. 18, which, by

means of the link 485, returns the bushing'482 clockwise to move thetenons 48| out of alinement with the slots 488.

if me selecting plates m andas: (Figs. 15 4and 18) are so positionedthat the largest radii -thereof are vopposite the .feeler fingers 499and 49| ,-the lever 488 will be prevented from moving in unisontherewith.' This will result in no movement being imparted to thebushing 482, and consequently the tenons 48| will remain out ofalinement with the slots'489 in the bushing 419. When the raised portion411 (see also Figs. 19, 20, and

2l) of the hub 414 moves beyond the camming lug 418 on the face of thebushing 419, the tenons 48| of the bushings 482 will engage the face ofthe bushing 419 to retain the plate 41| and the disk 412 in ineffectiveposition, as shown in Fig. 21. Consequently the stud 419 and recessedportion 498 of the disk 412 will remain out of alinei the total controlkeys for selectively controlling I the feeding of the audit strip.

' Method of operation In explaining the method of ,operating the presentmachine, letus take as an example a public utility company supplyingelectrical current and gas to' a plurality 4of consumers in a largecity. Each consumer has a meter to measure the consumption of electricalcurrent in kilowatt hours and a meter to measure the consumption of gasin `cubic feet. A city is generally divided into districts o f theproper sizeto be handled by oneemployee, whose duty it is to read themeters in his district periodically, generally once a month. Eachdistrict is subdivided into routes, each route being of the proper sizeto be covered in oneday by the meter reader. There is a meter readersbook for each daily route, and these books contain in logical order andupon individual sheets the name and address of each subscriber and theroute number, together with the meter readings from the previous month.

' The meterreader copies the present electric and gas meter readings oneach consumers chart or sheet and manually subtracts `the previousreadings from the present readings and lenters these differences, whichin the first instance is the kilowatt hours of electricity consumed andin the second the cubic feet of gas consumed, in the proper place uponthe sheet. At the end of the day the book for the route covered isturned over to the audit department, where the rate is figured fromchartsand the -cost'of the electricity and gas consumedl entered uponeach subscribers sheet.

From the audit department the meter books go to the billing department.where individual bills or statement slips are made out from datacontained in said meter book. An accounting machine similar to the onedescribed herein is generally employed in printing the statement slips.j

. With the totalizers of the machine clear, the operator begins to makeout the statement slips for aparticular meter book. After all of 'thebills or slipsr are made out for that particular l dicesse book, the'totalizers are cleared and the portion of the audit strip (Fis. il)covering the computations for said particular bool: is removed from themachine and accompanies the book to the checking department, where thestatement slips and the audit strip are checked against the meter book.All the meter books for the diierent routes are treated in this manner.

Since this divisional application relates particularly to the auditstrip and the control cfits ieedlng 'and the control of the impressionsthereon, the'statementslips referred to above, and also the meclflanismfor printing upon and controlling those strips, is not shown herein andreference may be had to the parent case if a .description thereofisdesired.

After properly inserting the statement slip, which is referred to in theparent case, in the machine, the operator sets up on the keyboard theprior electric meter reading, in this case 32092, d epresses the Priorkey 55 (Fig. l), and releases the machine for'operation by depressingthe motor bar E3. This causes the prior electric meter reading to besubtracted from the previously cleared No. i or add-subtract totalizer.

It will be recalled that only the seven higher denominational rows ofamount keys 59 are used forprlnting the prior and present meterreadings, as the two lower denominations do not have zero elimination,which makes them unsuitable for this purpose.

During this operation of the machine, the prior electric meter readingls simultaneously printed in the proper columns of the "Bookkeepingcoupon and Consumer's bill" of the statement slip and upon the auditstrip 4M, a fragment of which is shown in Fig. 8.

Next, the present electric meter reading, 32172, is set up on thekeyboard, and the Present K WH key 5S depressed, which, when the machinels operated, causes the present meter reading to be added to thecomplement of the prior meter reading contained in the add-subtracttotallzer, the result being the diderence between the prior and presentmeter readings. Also during this operation the present electric meterreading is printed in the proper columns of the statement slip, shown inthe .parent case, and the audit strip M3, and in both cases upon thesame line as the prior meter reading.

Immediately following this operation there are and present meterreadings, which is the kilowatt hours of current consumed, in thedifferent columns of the statement slip and the audit strip. In thesecond automatic machine operation the amount of kilowatt hours consumed(80) is automatically repeated and added into a grand totalizer forkilowatt l-^urs, represented by the "i e key B8 in the A'st transactionbank.

In the next machine. operation the operator sets up the amoun.A ci thebill, in this case $6.30, which is obtained from. the meter reader'sbook,- depresses the rate key 5B in the third transaction bankcorresponding to the amount of current consumed. and the "Multiple item"k'ey 58 in the rst transaction bank.v Releasing t e machine'foroperation causes the 'amount s .30 to be added in the proper ratetotalizer, selected by the key depressed in the third transaction bank,in a Total selec. totallzer located inthe ser position oi the No. 2line. selected by depr any of thekeys te in the third tr y. in ction andthis amount is also added in the "Multiple item totalizer on the No. iline selected by the Multiple item key de. disc in this operation theamount of the electric bill, $6.307, is printed in the amount columnoithe audit strip MB.

ln the next column the prior gas meter reading (67933) is set up on theamount keys, the Prior key 5d depressed, and the machine released foroperation by 'depressing the motor bar d3. During the initial partof'this operation the statement slip and the audit strip lili areline-spaced, which is eected by depressing thelidultipleitem key ES inthe preceding operation. In this operation the prior gas meter readingis printed upon the statement slip and upon the second line in theproper column or the audit strip des, and this prior meter reading isalso simultaneously subtracted from the cleared No. i or add-subtracttotalizer.

In the next operation of the machine the present gas meter reading(67963) is set up on the keyboard, the Present 16GB cu. it. key @tdepressed, and the machine released for operation. During this operationof the machine the present meter reading is printed in the propercolumns of the statement slip and the audit strip, and simultaneouslyadded to the complement of the prior meter reading contained in theaddsubtract totalizer. The result of this computation is the diiierencebetween the present and prior meter readings (30), which is the hundredcubic .feet of gas consumed by the subscriber.

In the first of the two succeeding automatic operations, theadd-subtract totalizer is cleared and the difference between the presentand prior meter readings (30) is printed in the proper columns of thestatement slip and the audit strip w3. In the second automatic machineoperation the dierence (30) between the present and prior gas meterreadings is added in a grandl totalizer for the gas consumed representedby the .100s cu. ft. key 66 in the rst transaction bank.

In the next machine operation the price of the gas consumed, in thiscase $3.60, is set up on the amount keys, the proper gas rate key 57 -lnthev second transaction bank and the Multiple-item" key S6 in the firsttransaction bank are depressed. and the machine released for operation.-In this operation the amount ($3.60) is printed on the statement slipand in the amount column of the audit strip 4M. This amount ($3.60) isalso simultaneously added in the proper rate totalizer on the No. 2 lineselected by the key depressed in the second transaction bank, and ina"Total t gas totalizer located ln the zero position ot the No. 3 line,selected by depressing'any key 5I in the second transaction bank. Thisamount is likewise added to the amount of the electric bill contained inthe fMultlple item totallzer located on the No. l line and selected bythe Multiple item key $6.

In the nal operation the Multiple item key 58 in the `first. transactionbank, together with the Reset key 65 for the rst transaction bank, isdepressed and the machine released for operation. At the beginning of.this operation the statement slip and the audit strip are again line-Vlzer is cleared and the total amount ol' the bill. $9.99, is printed onthe statement slip and in the amount column of the audit strip lll.

lt is estimated that 90% of the errors made by meter rers are insubtracting the prior fromv the present meter readings, to determine theconpticn, and only o! the errors are made spaced, after which theMultiple item" totaloperation for thatitem, 'when the amount of thebill, $6.30, is printed, instead of depressing the Multiple item keyinthe first transaction bank,

the Single item? key 56 is depressed. This y causes the bill to bereturned-forwardly near the end -of the machine operation and presentedto the ejecting mechanism.

After all the statements have been made out for a particular meter book,the KWH" totalizer on the No. I line is released to print the grandtotal kilowatt hours consumption (1826) upon the audit strip. This isaccomplished by depressing the KWH key 56 in conjunction with the firstbank Reset key 55 and releasing the machine for operation, by means ofthe Motor bar 53.

Next, the grand. total ($114.50) of electric amounts is printed upon theaudit stripby clearing the.Total Elec." totalizer on the No. 2 line.This is accomplished by' depressing the second bank Reset key 55 andreleasing the machinev for operation.

After this the grand total(1600) of the hundred cubic feet of gasconsumed is printed upon the audit strip by clearing the 100s cu. ft.totalizer on the No. I line. This is accomplished by depressing the 100scu. ft. key 56 in conjunction with the rst bank Reset key 55 andoperatingl .the machine.

Finally the Total Gas totalizer on the No; 3 line is cleared to printthe grand total ($155.10) of 4gas amounts upon the audit strip. This isaccomplished by depressing the third bank Reset key 53 and releasing themachine for operation in the usual way.

After this, the meter book, the statement slips.

for that particular book, and the portion of the audit strip 403containing all the transactions in said particular book are placedtogether and turned over to the audit department for checking. In thisnal check-up the mechanical'en- 'tries on the audit strip 403 larecompared with the entries in the meter readers book, and the amountsarrived at by the auditing department. This latter includes a grandtotal of the electrical current consumed, a grand total `of the cost ofthis-current to the consumer, a grand total of the gas consumed, and agrand total of the cost of this gas to the consumer.
